.Application filed February 24, 1926. Serial No. 90,334.

The invention relates to vehicle direction signals and has for itsobject lto'provide a device ot' this character con'iprising an elongatedcasing transversely disposed and Secured to the forward side of theautomobile body, forwardly of the windshield and having its end open. A-pointer slidably mounted within said casing and supported by contactmembers when outwardly projected and by a` centrally disposed rotatablegear withiu the casing, and'which gear cooperates with a longitudinallydisposed rack carried by the pointer.

A furtheriobject is to provide the pointer member with a longitudinallydisposed recess, the upper side of which is provided with a gear rack,with which the rotatable gear meshes and to proportion said recesswhereby the lower side thereof will engage the lower side of the gearteeth and maintain the gear in mesh with the rack and the ends of therecess will cooperate with the gear for limiting the outward movement ofthe pointer in either direction.

llith the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it. being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

y ln the drawings Figure 1 is a perspective view of a portion of aconventional form of automobile, showing the direction signal appliedthereto.

Figure 2 is a vertical longitudinal sectional view through thesignalling device.

Figure 3 is a horizontal sectional View through the central portion ofthe signalling device.

Figure d is a top plan View of the pointer.

Figure 5 is a vertical longitudinal sectional view through one end ofthe pointer and the casing.

Referring to the drawing, the numeral 1 designates a conventional formof automobile, and 2 the windshield thereof. Secured to the forwardportion of the automobile l forwardly of the windshield 2 is ahorizontally and transversely disposed casing 3, which casing isrectangular shaped in vertical cross section. Secured within the openends of the casing 3 are spring contact arms 4 which slidably engage theupper and lower sides of the elongated pointer 5 when either end of saidpointer is projected to the right or left for a lsignalling operation.The spring contact members 4 engage conductor plates 6 carriedy by theupper and lower sides of the arm 5, and which contact plates are incircuit with the electric lamps 7 through the medium of the conductorwires 8, and which lamps are disposed in recesses 9 of the pointer ends.It will be noted that the outer ends of the pointer are bevelled as at10, and when the pointer is forced outwardly in either direction, thebevelled surfaces will engage the spring contact arms et and spread thesame to a position where th'ey will engage the conductor plates 6. Itwill also be noted when the pointer is extended in either direction forindicating a` right or left turn, the outer end of the pointer will besupported by the spring contact arms, which will not only form circuitclosing means, but will also prevent rattling of the device wit-hin thecasing 3.

Extending transversely through the casing 3 and rotatably mounted in abearing 11 of theinstrument board 12 of the automobile is a shaft 13,the inner end of which is provided with a crank 14 adapted to be graspedby the operator for rotating the shaft 13 in any desired direction.Shaft 13 is provided with a gear 15 within the casing, which gear isdisposed in an elongated opening 16 in the pointer 5 and meshes with arack 17 carried by the upper side of said opening, therefore it will beseen that when the gear 15 is rotated in either direction the arm 5 maybe vforced outwardly from the open ends of the Vcasing according to thedirection of rotation of the gear. The outward movement of the ends ofthe arms 5 is limited by the engagement of the gear 15 with the ends 18of the opening 16, therefore it rwill be seen that the ends of theopening formlin'iiting means for limiting the movement of the signallingarm 5. The lower side 19 of the opening 16 engages the outer faces ofthe gear 15, and maintains said gear 15 in mesh with the rack 17 at alltimes, thereby obviating the necessity of special guiding or holdingmeans for the gear.

From the above it will be seen that a vehicle direction signallingdevice is provided which is extremely simple, the parts reduced to aminimum and one wherein the operating gear at all times supports theinner end of the lpointer thereby preventing rattling of the inner endof the pointer within the casing and the spring contact members 4support the outer end of the-pointer, and by providing the elongatedopening 16 the bottom 19 and the ends 18 of which Cooperate with thegear l5, the movement of the arm 5 is limited in its movement in eitherdirection and the gear Al5 `maintained in Amesh ait all times. A

Theinventionhaving been set forth what is claimed as new -and useful visl. A 'vehicle direction signal kcomprising a transversely -disposedelongated `easing having #its opposite side open, an elongatedsignalling arm disposed in said easing, a ytransversely disposedoperating shaft, said operating shaft extending transversely f nthroughan elongated opening in the signailing arm, a gear carried by said shaftand disposed 1n -the opening oiE the arm, a

-iraek `carried by thenpper side of the opening of the arm and withwhich the gear meshes, the ends of said opening cooper'- ating withopposite sides of the gear for limiting the outward movement of the armin either direction, 'said gear engaging the lower side of the openingduring the movemen't of the arm whereby said gear will be maintained 1nmesh with the rack.
